Above Ground Pool Pump Not Working (Quick Fix)

A Series of components work together in your swimming pool to give you clean water and a smooth swimming experience. Almost every component is inevitable, as they individually contribute immensely.

Amidst all these, a pool pump refusing to work should pull a lot of anyone’s concern as it is the major circulatory system tool. The inability to work doesn’t make it faulty, it might just need little servicing and you will be good to go.

On the other hand, if the pool pump is pre-exposed to lack of maintenance and harsh environmental influences, you might need to replace it or buy a fraction of it.

Above Ground Pool Pump Not Working

Why Will An Above-ground Pool Not Work?

Many reasons might contribute to your above-ground pool pump not working. The problem revolves around either the electrical part of the pump or the mechanical part of the pump. Your approach to resolving your pump will depend on your diagnosis. Below are common reasons your above-ground pool pump isn’t working:

  1. Electrical error: If any of the cable connections, timer connector, GFI and the breaker have burnt parts or an electrical shortage, the pump will never work. This might result from lightning, exposed wire due to shoveling or a weed eater, and even poor wire connections. It is the first thing to check when your pool pump stops working.
  2. Aging: The average pool pump electric motor uses not more than 5 years before it screams for a replacement. If your above-ground pool pump is up to 5 years, even without any maintenance error, it might not escape replacement.
  3. Water leakages: You will never see the full output of your pool pump if there is a leak somewhere. As the pump tries to pull water around, the leaks make the water level drop. When it gets to a certain level, the pump wouldn’t have enough water to function again.
  4. Mechanical faults: Several sections contribute to the effectiveness of your pool pump. Faults in the impeller, motor shaft, strainer housing, and another component of the pump system can cause a stoppage of function. Too much air content and loss of prime also fall under this section.


Detecting the area affected is simple if you can carefully check through. The section below is about diagnosis and the solutions advised for each case.

Solutions to an above-pool not working

  1. The pump doesn’t turn on: Go for the electrical connections. Check for burnt parts in the physical parts, look out for broken fuses in the breaker box, and check if you are supplying the right voltage. Seek the service of a professional electrician.
  2. The pump stopped pumping after working for some time: Does the motor shaft work? Can you hear the sound of the impeller? If not, it might be overheating. Check if the fan isn’t clogged with dirt or debris. What sound does it give?
  3. The pump gives humming sounds: Can you figure out where it hums? If it’s towards the impeller housing, turn off the pump, loosen the screws in the housing components, and remove the gaskets. Carefully clean off the debris stuck. If after this, the pump motor still gives a humming sound, your impeller can be stuck due to rust, or either the capacitor or the centrifugal switch.
  4. The pump works but the water volume is low: A component is blocked with debris, there might be too much air in the pump, or the pump simply needs to be primed. Check the pool filter basket and impeller to see if nothing is clogging it. If your filter gauge shows a reading more than 10psi of your normal readings, it’s time to clean the filter. For air leaks, check the o-rings and the skimmer baskets. If there are cracks in your o-rings, it is time for a replacement. If after all these, you cannot rectify the problem, seek professional aid from pool stores.
  5. The pool screeches: The sound of high-pitched sounds signifies two metal parts rubbing themselves. It’s a mechanical fault. Is the water level high enough? Low water levels can make the pump screech. In many cases, the bearings of the motors will be worn out and hence the noise. You can call a professional to help you replace the bearings in the motor. Sometimes, soft hitting of the motor might kick-start the pump, but that is only of the bearings’ damages are still in the early stages.
  6. The pool pump leaks: This is commonly caused by misfitting of o-rings. The o-rings crack off from aging. The thread sealant and the motor shaft can also be the ones affected. Check for faults in them. Replace the ones you find damaged or cracked.
  7. There are air bubbles or air suction in the pump: It might be a faulty valve, pump lid, suction pipes, thread sealants, o-rings, or gaskets. The signs you will notice are air bubbles in the pump lid, the pump basket not filling up with water or a prolonged pumping timespan. You can easily check for the affected parts yourself, and replace the needy. If you cannot figure it out, seek professional help.
  8. The pool pump leaks continuously after all efforts: The motor shaft’s seal is probably damaged. Ask for recommendations from your local pool store. A professional has to diagnose it by checking all the components personally.
  9. The pool pump requires priming almost every time: If you have done everything advised in this article before and your pool pump still loses prime almost every time, it might be a sign of the need for a new pool pump.


How Do I know My Pool Pump Isn’t Affected By Aging?

A pool pump has an average lifespan of 8 years. If your above pool pump has surpassed that much, it is time for a new one. Your climatic conditions will also contribute to the sustainability of a good workflow of your pool pump. If the current supplied for electrical functions are below or above recommendations over time, it will affect the functions as it ages too.



You can simply replace affected parts after diagnosis by ordering them online or getting them in your local pool store. If you have trouble fitting it perfectly, seek professional help.
